TrishB you can do an introductory online course here www.sofst.org in machine embroidery for £75. They do other online courses as well, including City & Guilds. I'm considering taking the course myself.
Has anyone checked You Tube. Neither have I, but I will as a matter of interest as soon as I have signed off GN. I brought my all singing dancing sewing machine from John Lewis about 6 years ago (but it is hardly used as I still have to work full time) and the rep who sold it told me that the Chinese ladies in this area (Milton Keynes) were hot, hot, hot! But I never see anything for sale so what they do I have no idea.
